There can be little doubt that Homo Sapiens is the most dangerous predator the world has ever produced. We have enormous brains capable of building systems to overcome friction, the ability to accomplish complex planning within those systems, and opposable thumbs to assist in the execution of the plan. We have canine teeth and forward-looking eyes. We are the most accomplished killers in the animal kingdom, exceptional when hunting alone, but capable of cooperating in large groups to make a kill.
